Choose Vanta when

You need an established vendor with 200+ pre-built integrations to SaaS tools you already use.
You want a turnkey SOC 2 program with vendor-managed continuous monitoring.
Your team is comfortable shipping evidence to a third-party cloud.
You want the brand-name effect during a sales process.

Choose Probatum when

Your data residency story matters: PHI, CUI, classified, on-prem only.
You want pricing visible up front — no demo gate, no quote dance.
Your auditor wants verifiable, signed evidence — not dashboard screenshots.
You need AI-governance frameworks (EU AI Act, ISO 42001, NIST AI RMF) in the same tool.
Hallucinations entering evidence is a deal-breaker — you need grounding scores on every claim.

Vanta is the market leader. They sell scale, ecosystem maturity, and a polished “Vanta Agent” story. Probatum sells a different category: trust by cryptography, not by dashboard.
